Baer Heli Coil Tap - Wire Thread Insert - Bottoming Tap (STI) - BSF - 1 x 10

The Baer Heli Coil Tap is the precise, purpose-built tool you need for impeccable thread repairs and reinforced fastener reliability. Designed to work with HeliCoil wire thread inserts, this bottoming tap delivers clean, true threads that stand up to demanding service and repeated assembly cycles. If you’re restoring damaged holes or adding durable, maintenance-friendly threads to new workpieces, this tap is built to perform with consistency.

Why this Heli Coil Tap stands out

• Bottoming design for full-depth threads: Reaches the bottom of blind holes to ensure complete thread engagement and reliable insert seating, every time.
• Durable HSS-G construction: Engineered for longevity under repeated use, maintaining sharp cutting edges and resisting wear in tough materials.
• BSF compatibility with 1 x 10 specification: Precisely matched to British Standard Fine thread standards, enabling accurate repairs and reinforcements for threaded assemblies.
• Optimized for wire thread inserts: Creates the ideal internal thread profile so HeliCoil inserts install cleanly with low risk of cross-threading or pull-out.
• Versatile, professional-grade performance: Suitable for a range of applications—from maintenance trades to precision fabrication—where strong, repeatable threads matter.

Perfect use cases

• Repairing stripped or damaged internal threads in equipment housings, transmission components, or engine-related parts.
• Adding reinforced threads in new or repaired holes where high load or vibration resistance is required.
• Retrofitting existing assemblies with durable inserts to extend service life and reduce downtime.

How to get the best results

• Align carefully with the bore to avoid cross-threading; ensure the tap is perpendicular to the work surface for true thread creation.
• Use a light cutting fluid or oil to reduce friction and extend tool life during tapping sessions.
• Make steady, evenly spaced turns; don’t force the tap — let the cutting edges do the work and back off periodically to clear chips.
• Pair with the appropriate HeliCoil insert for optimal grip and load distribution in the repaired thread.

Whether you’re a professional machinist, a maintenance technician, or a serious hobbyist tackling gear trains and assemblies, the Baer Heli Coil Tap delivers dependable, repeatable results. Restore damaged threads with confidence, reinforce critical joints, and keep machinery running smoothly with tools you can trust—built to the exacting standards you expect from Baer Coil.
